Following those ideas we implemented some tools for configuring a WorkingSet, a mean for filter which Facts you are able to use inside Guvnor’s Guided Editor. But that’s not all what we’ve been doing, you can also define for each field a set of constraints that will restrict what users will be allowing to write inside a rule.

Since a video worth like a thousand posts, I’ve created one showing the new features using the Guvnor demo model. in the video you’ll see how to create a new working set. Once the Working Set is created, it shows how to add facts and define constraints for those facts, as you’ll I defined a Range constraint for a credit Applicant’s age field. And next to demonstrate how to use a WorkingSet to verify a rule, I’ve created a new rule adding a restriction that would make the Range Constraint to fire.
